Choose the correct answer from the options given below.

To find the correct match, let us analyze each reaction given in List - I and identify its name from List - II:

(a) Benzene reacting with CO and HCl in the presence of anhydrous AlCl₃ and CuCl:
When benzene or its derivatives are treated with carbon monoxide and hydrogen chloride in the presence of anhydrous aluminium chloride (AlCl₃) or cuprous chloride (CuCl), it yields benzaldehyde or substituted benzaldehyde. This reaction is known as the Gattermann-Koch reaction.
Therefore, (a) matches with (ii).

(b) R-CO-CH₃ + NaOX → Products:
Methyl ketones containing the CH₃-CO- group react with sodium hypohalite (NaOX) to produce a haloform (CHX₃) and the sodium salt of the corresponding carboxylic acid. This reaction is known as the Haloform reaction.
Therefore, (b) matches with (iii).

(c) R-CH₂-OH + R'-COOH in the presence of concentrated H₂SO₄:
When an alcohol reacts with a carboxylic acid in the presence of an acid catalyst like concentrated sulfuric acid (H₂SO₄), an ester and water are formed. This condensation reaction is known as Esterification.
Therefore, (c) matches with (iv).

(d) R-CH₂-COOH reacting with (i) X₂/Red P and (ii) H₂O:
Carboxylic acids containing an α-hydrogen are halogenated at the α-position upon treatment with halogen (Cl₂ or Br₂) in the presence of a small amount of red phosphorus, followed by hydrolysis. This reaction is known as the Hell-Volhard-Zelinsky (HVZ) reaction.
Therefore, (d) matches with (i).

Combining all the matches:
• (a) → (ii)
• (b) → (iii)
• (c) → (iv)
• (d) → (i)

Thus, the correct option is (a)-(ii), (b)-(iii), (c)-(iv), (d)-(i).
